GAS SAVER FOE HYDROCARBON ENGINES.

Application filed Octobcr 14, 1921 To all whom it may concern:

Be it known that I, amra T. GREENE. a citizen of the United States,residing at RoXbury, Boston, in the county of Suffolk and State ofMassachusetts, have invented certain ne and useful Improvements in GasSavers for Hydrocarbon Engines; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

The present invention relates to an improvement in gas savers forhydro-carbon engines.

The object of the invention is to produce a gas saver for use in theintake pass; of an automobile engine of cheap and euicient construction.To this end the invention consists in the gas saver hereinafterdescribed and p:-irticularly defined in the claim.

In the accompanying drawings illustrating the preferred form of theinvention, Fig. l is a sectional elevation of a portion of a farburetorand intake manifold of an automobile engine provided with the gas saverforming the subject of this invention; and Fig. 2 is a front elevationof the gas saver shown separately.

The illustrated embodiment of the invention is described as follows :Theflange of the carburetor 1 is bolted to the flange of the intakemanifold 2, and between these two flanges is placed a gasket 3, providedwith a column of felt washers a, supported on a wire 5, the ends ofwhich are received between the two metallic surfaces of the gasket 3. r

The column of felt washers is arranged vertically in the horizontalintake pipe. and any fuel condensing on the walls of the pipe beyond thegas saver flows down the pipe to the column of washers. where it isabsorbed and lifted by the capillarity of the felt into position to beevaporated by the stream of fuel and air flowing through the pipe.Furthermore, any particles of fuel striking the column of felt washerswill be arrested and gradually evaporated, as a re sult of which themixture of air and fuel Serial No. 507,780.

will be more intimate. In addition to this. the column of felt washersacts to cause turbulence in the gases and vapors passing it, so asthereby to secure a more intimate mixture of the air and the fuel. Thefelt washers, by reason of their rough surfaces, increase thedisturbance of the air and fuel particles as they pass by them, becausethe column of washers acts with high skin frictional resistance to thepassages of the air and fuel by it. The use of felt washers isconvenient because any suitable number of washers may be usedcorresponding to the diameter of the opening in the pipe passage inwhich the gas saver is located.

lVhile it is preferred to place the column of washers in a verticalposition because in such position it absorbs any fuel running down thepipe toward the carburetor and presents it to evaporation by theiutlowing body of air, still benefits are derived from the use of thecolumn in a horizontal position, because of the rough surface which thecolumn presents to the body of air and fuel passing it, which body ofair and fuel is thereby caused, to be more intin'iately mixed. and thefuel to be more finely divided than otherwise.

The gas saver of the present invention preferably embodied in a gasket,as is shown in the drawings, in which form it constitutes a convenientarticle of commerce. the gasket constituting a support or frame forcarrying the column of felt washers.

It has been found in actual use that the gas saver of the presentinvention. when installed between the carburetor and manifold of a smallcar, effects an increase in mileage per gallon of fuel of from two toeight miles per gallon. This increase in mileage per unit of fuel is duein part to the fact that this gas saver permits the reduction of theamount of fuel supplied with a given quantity of air. Thus, in such acar, the ad justing screw for regulating the richness of the mixture maybe screwed down a considerably greater distance when this saver is used,and this is believed to be due to the fact that the mixture is renderedmuch more uniform by its use, with the result that the amount of fuelused per unit of air is (l0: creased, and the e'tficieney of the motor1S thereby lncreasecl.

Having thus 'clescrlbecl the invention, what 5 is claimed is: k

A gas saver for'liydro-czn'hon engines, eonslstlng of a gasket adaptedto he clamped between the surfaces of the connections of the intakepassage, :1 wire extending on one side of the gasket to the other nerussthe 10 opening therein, and a plurality 0t absorbent washers looselymounted on the wire.
